Mateial introductionBorosilicate glass is a type of glass with the main glass-forming constituents silica and boron oxide&period; Borosilicate glasses are known for having very low coefficients of thermal expansion&lpar;~3 × 106 &sol;°C at 20°C&rpar;&comma; making them resistant to thermal shock&comma; more so than any other common glass&period;In addition to the quartz&comma; sodium carbonate&comma; and aluminum oxide traditionally used in glassmaking&comma; boron is used in the manufacture of borosilicate glass&period; The composition of low expansion borosilicate glass such as those laboratory glasses mentioned above is approximately 80&percnt; silica&comma; 13&percnt; boric oxide&comma; 4&percnt; sodium oxide&comma; and 2-3&percnt; aluminum oxide&period; Though more difficult to make than traditional glass due to the high melting temperature required&comma; it is economical to produce&period; Its superior durability&comma; chemical and heat resistance finds excellent use in chemical laboratory equipment&comma; cookware&comma; lighting and&comma; in certain cases&comma; windows&period;Why you choose C&C Glass1&period;Heat resistant2&period;We have many style tea cup and tea pot let you enjoy your leisure life&period;3&period;Clear design makes you feel the liquid is floting in the glass teapot&period;4&period;The Borosilicate glass is amazingly durable&period;&period;&period;Because of this&comma; these glasses are more resistant to temperature swings and scratching&period; They are also dishwasher safe&comma; microwave safe&comma; and will not become cloudy over time&period;5&period;As nice as these glasses are&comma; they are still made of glass and will break if not handled with care&period; Please use care when placing ice into this glass to avoid fracturing the inner layer&period;&period;&period;also use care with metal spoons or placing the glass into a crowded dishwasher&period;

Why Us &quest;1&period; All our products are able to endure sudden temperature changes from -20°C to 150°C in extremely short time

Questions&colon; Are this kind of glass wares safe &quest; Does they easily broken and fragile &quest;Answers&colon; Borosilicate glasses are known for having very low coefficients of thermal expansion&lpar;-20°C--150°C&rpar;&comma; making them resistant to thermal shock&comma; more so than any other common glass&period;In addition&comma;it is much lighter in weight but more solid in molecular structure&comma;thus even with small thickness&comma;it also could reach high strong intensity and so more durable than traditional soda lime glass&period;C&C Glass uses high quality borosilicate glass and pay more special attention to the thickness of products&comma;make them thicker but firm and comfortable when you hold them&period;Therefore&comma;C&C products are one of the most safest and popular products in the market

2&period;Sophisticated Hand Blown Craftsmanship&comma;Uniform MoldAs a more advanced glass material&comma;Borosilicate glass were widely used in Chemical and Medical industry and High end Kitchenware in most European and American countries&period;With sophisticated mouth blown craftsmanship&comma;workers needs to constantly rotate the glass embryo in order to heat the glass uniform&period;This is the most significant special features of hand made glasswares compared with other glasswares

3&period;Clear borosilicate glass which is free of smell and flavor&comma;does not discolor and show high chemical and mechanical resistance&period;Therefore it is eco-friendly and safety to human body
